UNITED STATES JOHN o. WAGNER, or CHICAGO, ILLINOIS.

\ CAR-WINDOW SCREEN.

Application filed February 19, 1923. Serial No. 619,785.

To all whom it may concern. I

Be it known that I, .loIrN VVAoNEn, a citizen of the United States. anda resident of the city of Chicago. in the county of (look and State ofIllinois. have invented certain new and useful Improvements in aCar-VVindow Screen; and I do hereby declare that the following is afull, clear, and exact description of the same, reference being had tothe accompanyingdrawings, and to the numeralsof reference markedthereon, which form a part of this specification.

This invention relates to window screens especially of that type used oncars. and concerns itself primarily with means for securing the screenagainst liability of rattling and for .locking the same in an elevatedposition by a normally concealed member which is adapted to be broughtinto use when the screen is raised.

This invention comprises the novel mech anism and combinationshereinafter described and morev particularly pointed out and detined inthe appended claims.

In the accompanying drawings which illustrate. a preferred embodiment ofthis invention and in which similar reference numerals refer to similarfeatures in the different views:

Figure l is an elevatitmal view of the outer side of a car window.

Figure 2 is an enlargedfragmentary interior elevational view with partsbroken away showing the screen in elevated position behind the panel.

Figure 3 is an enlarged fragmentary bottom plan view of the screen withthe screen guideway shown in section.

Figure 4 is an enlarged broken and transverse section through a Pullmancar window construction illustrating certain features of this invention.

Figure 5 is. an enlarged broken section upon the line 5--5 of Figure 4with parts in elevation.

Figure 6 is an enlarged section upon the line 66 of Figure 5.

' Figure 7 is an enlarged fragmentary elevational view with parts brokenaway illustrating certain features.

In referring now to the drawings. it will be observed that the screencomprises :1 rectangular frame 1 of well known construction forretaining the foraminous sheet 2.

.the tools. may be passed for operating the screws.

. 0n the side of the. frame 1 through which the screws 3' pass aguideway in the form of a channel-like extension 6 is secured. Thisextension is formed from a sheet metal a plate which is stamped toprovide a channel- ]ikegroove with retnrned'sides which grip the'sidesof the frame 1 as shown in Figure 6; the screws 2) also extendingthrough the' web of the channel extension. A pair of leaf springs 7(Figure 5) are secured at one end to the web of the channel. extension(5 so as to be within the channel thereof directly over the screws 3which are adapted to contact therewith and press the same outwardly. p

()n the side of the frame 1 opposite the channel extension (5 there is aguidcway in the form of a channel extension '8 (Figure 4-) provided witha concave channel-like groove with returned sides which grip the sidesof the frame. The sides of the screen may therefore be said tobeprovided with guideways or grooves.

A convex guide strip 9 secured to the side of the window frame fits inthe guideway of the extension 8, while an extended guide 10 on theopposite side of the window frame fits in the guideway formed by theextension 6. The guide 10 is formed by stamping a metal plate with adeep channel-like groove forming thereby a forwardly projecting hollowguide tongue; the rear ends of the plate being stamped to provide anopen channellike groove for fitting over and securenient to an anchorstrip 11 secured to the side of the window frame.

Normally concealed within the hollow tongue '10 is a strut 12 pivotedintermediate its ends to the tongue 10 and swingable beyond the front oftheguideavhich is suit ably slotted for this purpose as shown in Figure7; An opening 12 (Figure 2) in the guide 10 allows the lower end of thestrut to be normally swung. The upper end of the strut 12 has its rearcorner cut away to 10 by sufiiciently produce a restrictedpro ection 13adapted to enter an aperture 14 mAjthe bottom of the frame 1 when thescreen has been sufliciently elevated and the upper end of the strut hasbeen swung forwardly.

The screen with the lateral guideways 6 and 8 secured thereto may bereadily placed in position with relation to the guides 9 and turning thescrews 3 inwardly so that the guideway 6 may be positioned over theguide 10 and shifted sufficiently to allow the guideway 8 to clear theprojecti0n9. Then by adjusting the screws 3' all play and slack may betaken up as is obvious.

I am aware that numerous details of construction may be varied through awide range without departing from the principles of this invention, andI therefore do not purpose limiting the patent granted, otherwise thannecessitated by the prior art.

I 'claim as my invention:

1. A screen comprising a frame, guide- Ways secured to the lateral sidesof the frame, leafsprings secured in one of said guideways, andadjustable screws concealed in said frame extending through the frameand into the last-mentioned guideway and into contact with said springs.

2. The combination with a screen having lateral guideways, of' guidesfor cooperating with said guideways, one of said guides being hollow,and a strut pivoted in saidhol- 'low' guideway and swingable therebeyondfor latching the screen in elevated position. In testimony whereof Ihave hereunto subscribed my name.

JOHN O. WAGNER.
